In-situ Ion Velocity Meter
Measures ion drift velocity in the spacecraft reference frame, the ion temperature and the total ion number density at the location of the spacecraft.
The IVM consists of two planar thermal ion sensors, a retarding potential analyzer (RPA) and an ion drift meter (IDM)
Derived from C/NOFS CINDI project
